DRINK .MIXER Application led January 25, 1929. Serial No. 334,945.

This invention relates to improvements in mixers and more particularly to drink mixers. One o the objects of my invention is the provision o a drink mixer provided with nov- -el means for applying and shutting od the riving power for the agitator whereby the l agitator may be readily rotated after being received into the receptacle and the driving power readily cut oli before removing the agitator from the receptacle. Another object of my invention is the provision of new and improved means formountp ing the driving mechanism so that parts thereci may be actuated at the will of the operator for imparting movement to the agitator'and includes means whereby the agitator is simultaneously moved with the movable parts of the driving means so that the agitator may be raised and lowered relative a receptacle.

A. further object of the invention is the provision of a drink mixer which' is provided with movable means for supportinga portion oi? the driving mechanism and additional means is provided for raising and lowering the first means at the will of the operator so that the agitator may be driven when so desired.`

With vthe above and other objects inview,

f the .invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth,

pointed outv n the claims A,and shown in the accompanying drawings wherein Figure 1 is a vertical sectional-view of my improved. mixer, parts thereof being illustrated in elevation;

Figure 2 is a side elevation;

Figure 3 is a section on theA line 3--3 of. Figure 1;

Figure 4 is a transverse section on the line 4-4 of Figure; f Figure' 5 is a detailed section on the line 5-5 of Figure 3.

1 In carrying out my invention, I preferably a motor 1, mounted upon a stationary -platform 2, said motor having upon its drivlng shaft a pul- Firtending upwardly from the base member 2 are the spaced standards 4 upon which is slidably mounted the housing 5 enclosing the pulley 3 and provided in its rear wall wlth a vertical slot 6 to receive the drive shaft fof the motor 1.

The housing 5 is provided with a lateral ovable top plate 8 vand a lower bearing sleeve 9. I 'Ihe top plate 8 is retained in place by means of set screws 1() and 11, the -screwflO passing through the top plate 8 and engaging within a threaded opening formed in the outer wall of the housing 7. The screw 11 passes through an upstanding flange on the top plate 8 and engages the upper portion of the housing 5.

Supported within the housing 5 at the inner end of the housing 7 is a bracket 12 supporting a shaft 13 having uponeach end a ulley 14. The 15, the shaft 16 of which is rotatably mounted in the bearing sleeve 9 and this pulley 15 is connected with the pulley 3 by means of a belt 17 which passes over the pulleys 14 as the pulleys 3 and 15 are disposed at right angles to each other, thus necessitating the turning of the belt as it passes over one pulley to the other, this turning movement being imparted to the belt by having the same passing over the pulleys 14. I

Thehousing 5 has at its lowerk end a laterally projecting shelf part 18 which extends voutwardly from the front wall of the housing and extending upwardly from this shelf are the spaced guide rods 19, the upper ends of which are received in suitable sleeves 20 carried by the housing 7.

- The machine is'particularly designed for use in mixing drinks and particularly drinks where the {luid body is comparatively heavy or thick and for this purpose I provide a comparatively heavy cup-like receptacle 21 having a handle 22 at one side, and a heavy flanged bottom 23, the flange on the bottom extending a short distance beyond the side wall of the cup. On the lower endof the shaft 6, I mount an agitator which is in the form of a yoke 24 having a. connecting cross piece 25 for the ends of the yoke.

The shaft 16 is surrounded by an Velongated bearing sleeve 26 upon which is slidably mounted a sleeve 27, closed at its lower end and carrying a disc like shield member 28, which is used for closing the cup 21 when in its operative position as shown in Figure 1.

In order to normally urge the shield member 28 downwardly upon the shaft 16, a coil spring 29 is mounted upon the shaft 16 with in the sleeve 27 and disposed between the lower end of the elongated bearing sleeve 26 and the lower yclosed end of the sleeve 27.

From this, it will be apparent that when the shield 28 is disengaged from the walls ofthe cup, the spring 29 will force the same housing 7 encloses a pulley` of the housing 5 and is engages with the a tilting plate like memberl which has lugs 32 upon its lower edge mounted within suitable recesses in the transverse plate 33 attached to the inner side of the front wall of the housing 5.

This plate 31 Vis normally maintained in an upright position by meansof the spring 34 on the pin 35, vthe pin being carried by the' plate 33 Aand the spring 34 being disposedr between the plate 31 and the head of the pin as illustrated in Figure 4, so that the ten-4 sion of the spring will maintain the plate 31 in its normal position.

Extending laterally from the upper edge of the plate 31 and passing through an opening in the front wall with its jeeting beyond the front wall, is a stop member 36 which has a lower cam like face 37, the upper face of the stop being preferably disposed in` a horizontal plane. From this it will be apparentl that when 'the cup 1s moved upwardly for engaging the shiel 28 with the inner wall of the cup. the flanged bottom of the cup will contact the cam facev 37 rocking the plate 31 to permit the flange to pass upwardly above the stop member 36, and as the iiange passes the stop 36, the spring 34 will return the stop toits normal position as shown in Figure 1, to form a rest for the cup. When it is desired to release the cup, the plate 31 is Vmanually rocked upon its pivot by engaging a thumb piece 38 on the outer end of a pin 39, ,which extends through an opening in the front wall engagedA with the plate 31 to rock the same upon its pivot.

It will be appa-rent that in placing the cup 21 in position, the cup is moved inwardly until it engages the guide rods 19 and as the cup moves upwardly, the lower end of the same is pushed inwardly until the flange bottom contacts with the guide members so that,V

,l this flange will engage'the stop 36 and pass above the same as described above.

In Figure, 1, I have illustrated the dev1ce as in an operative position, and in Flgure 2,

' I have illustrated the device in an inoperative l raising and lowering operation is performed position in dotted lines.l v When the 'device is in an 1noperat1ve position as shown by the. dotted lines of Figure 2,

the belt 17 is in a slack condition so that it does not engage the pulley 3 and no 'move-A ment is imparted to the pulley 15, shaft 16 and the agitator, this bein carriedxout b raising and lowering the ousing 5. `This 'by having the hand lever 40 pivoted on the pin 41 which is carried by one of the standards 4, a slot 42 being formed in the wall v`of the 'with a Vhandle 46 which outer end pro- .movement moving the housing y housing 5 -to permit the housing to move relative the pin.

The lever 40 is fulcrumed on theV pin 41 and one end of the connected as at 43 to link 44, the lower end of thej link bein pivotally connected to the housing 5 as s own in 45.

The outer end of the lever 40 is provided may be grasped by the hand of the operator for rocking the lever upon its pivot.

It-will b e apparent that when the device is in an inoperative position, the parts are positioned as illustrated by the dotted lines 1n Figure 2 with the lever 40 and the link 44 lying parallel withthe housing 5, this position drops the lower loop of the belt 17 downwardly from engagement with the` pulley 3. After the cup has been placed in an operative position as shown in Figure 1, with its flanged bottom resting on the stop 36 `and the shield 28 engaged with the inner wall of the cup, the housing 5 is moved upwardly by grasping the handle 46 ofthe lever 40 and pulling the lever 40 downwardly to the position shown in Figure 2, this movement of the lever exertin an upward pull on the lever 44, which in lturn will move the housing 5 upwardly, the

slot 42 permitting the housing to move relative the pin 41-and tightening the belt 17 so that the same will be brought into engagement with the pulley 3 to imparta rotative movement to the shaft 16 and the agitator within the cup.

During the mixing of the contents of the cup 21, the lever 40 is maintained in its operative position by the operator and after the drink has been properly mixed the lever 40 is moved back to its inoperative position s h'own by the dotted lines in Figure 2, this p 5 outwardly to disengage the belt 17 from the pulley 3.

During the mixing of the drink some of the ingredients will have a tendency to adhere to the lower face of the disc like shield 28 and in order to remove theseparticles, the cup is dropped downwardlyuntil its flanged bottom rests upon the shelf 18, this operation being carried out by pushing inwardly on'the pin 39 to release the stop 36 from the bottom of thecup. The cup having been 'dropped .disc 28 may be removed before the cup is entirely removed from the device.
